数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

研究者根据受试者的原始观察记录,将数据完整、及时、正确地载入病例报告表,采用相应的数据库系统输入,之后对数据库进行对比。电子数据文件分类保存,并有多个备份保存于不同磁盘及介质上,妥善保存,防止损坏。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Based on the original observation records of the subjects, the researchers will write accurate data into the case report in time, and input it into the corresponding database system, and then compared the database. Electronic data files are classified and saved, and multiple backups are saved on different disks and media, properly saved to prevent damage.
